通过本地Exim MTA用python发送电子邮件

Question

I'm trying to create an automated system on my Arch Linux VPS that will send a monthly, HTML formatted, report to my e-mail. 我试图在Arch Linux VPS上创建一个自动化系统，该系统将每月以HTML格式发送报告到我的电子邮件中。 I've decided to use python as the programming language for that, however I find myself stuck. 我决定使用python作为其编程语言，但是我发现自己陷入困境。

In the code below you'll find that I use the SMTPlib to build and send a message. 在下面的代码中，您将发现我使用SMTPlib来构建和发送消息。

import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText


def py_mail(SUBJECT, BODY, TO, FROM):
    """"With this function we send out our HTML email"""

    # Create message container - the correct MIME type is multipart/alternative here!
    MESSAGE = MIMEMultipart('alternative')
    MESSAGE['subject'] = SUBJECT
    MESSAGE['To'] = TO
    MESSAGE['From'] = FROM
    MESSAGE.preamble = """"Your reader does not support the report format. Please visit 
                            us <a href="https://my-website.nl">online</a>!"""

    # Record the MIME type text/html
    HTML_BODY = MIMEText(BODY, 'html')

    # Attach parts into message container
    MESSAGE.attach(HTML_BODY)

    # Create SMTP object
    server = smtplib.SMTP(host='localhost', port=587)

    # Print debugging output when testing
    if __name__ == '__main__':
        server.set_debuglevel(1)

    # The actual sending of the email
    try:
        server.starttls()
        server.sendmail(FROM, [TO], MESSAGE.as_string())
        server.quit()
    except smtplib.SMTPException as error:
        print("Error: unable to send mail : {err}".format(err=error))


if __name__ == '__main__':
    """Executes if the script is run as main script (for testing purposes)"""

    email_content = """"
    <head>
        <link href="https://fonts.googleapis.com/css?family=Open+Sans+Condensed:300" rel="stylesheet">
        <meta charset="UTF-8">
        <title>TestMail</title>

        <style>
            h1 {
                position: absolute;
                top: 50%;
                left: 50%;
                -webkit-transform: translate(-50%, -50%);
                -moz-transform: translate(-50%, -50%);
                -ms-transform: translate(-50%, -50%);
                -o-transform: translate(-50%, -50%);
                transform: translate(-50%, -50%);
                font-family: "Open Sans Condensed", sans-serif;
                font-size: 3em;

            }
        </style>

    </head>
    <body>
        <h1>'tis but a scratch</h1>
    </body>
    """

    TO = 'to-email@website.com'
    FROM = 'from-email@website.com'

    py_mail("Test email onderwerp", email_content, TO, FROM)

But once I run the script i get the following error: 但是一旦运行脚本，我将收到以下错误：

ConnectionRefusedError: [Errno 111] Connection refused ConnectionRefusedError：[Errno 111]连接被拒绝

I have Exim running as a local, send-only MTA on my server. 我有Exim作为本地MTA运行在服务器上。 I have no problems sending e-mails via the command line. 我通过命令行发送电子邮件没有问题。 Problems only start occurring once I try to connect to it with Python. 仅当我尝试使用Python连接到问题时，问题才开始出现。

If anyone can help me out that'd be awesome. 如果有人可以帮助我，那就太好了。 Thanks in advance 提前致谢

Do you really have an SMTP server running on the localhost port 587? 您真的在本地主机端口587上运行SMTP服务器吗？ Try port 25 — it's the standard port for SMTP. 尝试端口25-这是SMTP的标准端口。 587 is for SSL/TLS but you have to configure your SMTP for that. 587适用于SSL / TLS，但您必须为此配置SMTP。

If you're sure it must really be port 587 — check firewall settings. 如果确定确实是587端口，请检查防火墙设置。
